Page 3: Description
1. Description: Emitors TVLOOK is developed in Sweden for working together with all kinds of TV and Radio signals between 2-900 MHz. TVLOOK operates the frequency-range of 2-900 MHz and is accordingly one of the first to be able to work with the return-path signals in Cable-TV networks (5-65 MHz) this in conjunction with the new EN50083 standard. -
Page 4: Operation
Use the mainswitch to turn the instrument On and connect an signal-source via the BNC- connector. After a few seconds warm-up the TVLOOK starts showing the frequency spectrum of 2-900 MHz on the picture-screen and the main-menu on the LCD-display. -

All measured data can be memorized and transfered to a computer. More of this later in this manual and in the attached TVLOOK-software manual. -
Page 7: Reference Cursor And Signal/Noise Ratio
• The relation between cursor nr 1 and cursor nr 2 is presented in the lower right hand corner of the picture-screen. D. Digital measuring. TVLOOK can also measure, so called, Digital dB i.e. the output-level of Digital transponders (like Digital terrestrial transmissions). Simply input the start and stop frequencies of the transponder to measure on (a Digital transponder is normally 8 MHz wide) and TVLOOK presents the measured and corrected value (dBuV) in the picture-screens lower right hand corner. -
Page 8: Memory
D. Memory. All spectrum-pictures can be saved (memorized) in the TVLOOK. This is very useful as new installations, service and maintenance work can be documented. Later on, the memory-positions can be easily transfered to a standard PC (with help of the attached PC-software) and written out on the PC´s printer. -

(12) K. Favourite channels. Thanks to the powerful processor, TVLOOK can measure up to 10 pre-set channels at the same time (and it can be setup with 10 pages of 10 channels each). This is done by choosing the channels(frequencies) to measure on and programme them in the favourite channel memory. -
Page 14: User Span
These working-areas might differ a lot depending on where the instruments are being used (geographically) or by whom. For that reason the TVLOOK has the unique possibility to do a individual setup of such frequency-bands. Programming the frequency-bands, do like this: * Chose a frequency-band to programme (for ex. -
